Pet Preforms
Injection molding machine setters set up and tend machines that transform Pet Preforms plastic compounds into a wide variety of consumer goods; such as, toys, tubing, and auto parts. They install plastic injection molds on the molding machine; make necessary connections of the electrical, hydraulic and cooling systems to the mold; insure that the correct plastic material, plastic melt temperatures, shot size, injection speed and pressures are set; and cycle the machine and adjust the molding parameters until acceptable parts.Injection mold changes can be performed quick if the molds are ready for use when they leave the stores and can go into production without the need for major assembly or cleaning work. Every injection mold must therefore be a self-contained unit, i.e., it must not be made of parts that are required for other injection molds. Parts or groups of parts that are loaded or borrowed often disappear or are need elsewhere just when the injection mold is scheduled for use.
great list, i must say very good picks
